Polls sliding door roller

Thanks for posting. Pella doors often use the 81-098 (there is also a generic version of this roller, the 81-249) or the 81-244. But I am afraid there is no way of knowing if either of these rollers are what you need. You will need to remove your old ones from the door and compare to confirm if either is what you require.
